Boiler Room

Boiler Room is a mining-themed slot with six reels, four rows and 1,024 ways to win. It has an RTP of 96%, high volatility and a maximum win of 5,282x.

A Flame Wild substitutes for all regular symbols except the Steam Valve scatter. The Steam Valve scatter pays from any position and triggers Meltdown Mode when three or more land in a spin.

Meltdown Mode awards 8, 10 or 12 burn cycles at the start. A pressure gauge with named zones determines the multiplier applied to all wins during each cycle. Winning spins raise the gauge by one zone while losing spins lower it by one zone. During the feature, three or more Burn Cycles scatter symbols retrigger Meltdown Mode and award four extra burn cycles.

The Bonus option costs 100x the spin stake and enters Meltdown Mode directly, starting in the Cold zone. The Super Bonus costs 500x and begins at the Hot zone with altered pressure mechanics: wins advance two zones instead of one, while losses deduct only one zone. The Super Bonus can reach a maximum multiplier of 50x within Meltdown Mode.

Super Boost costs 2x per spin and improves the trigger chance for Meltdown Mode, remaining active until the feature triggers or the player disables it. Hyper Boost costs 10x per spin and greatly increases the trigger chance, staying active until Meltdown Mode lands or the player turns it off.
